RacalDana1992

For sale is a Racal-Dana 1992 Universal nanosecond counter. Military surplus. Unit powers up, but I could not figure out how to make it work. This is a very powerful unit, counting frequencies into a very high range 0-1.3GHZ (see pictures). :SATISFACTION:

Answers to questions

Does it come with power cord and manual? Yes, it comes with a standard computer style power cord, but without a manual. Tom Gootee sells a manual for it on eBay.

Can you supply extra pictures? Yes, see them here. I cleaned the cabinet a bit, without removing calibration tags. Sorry for the mess on the desk.

On the rear panel is an option tag. Is anything stamped on that tag? ANSWER: There are no options listed. Serial number 992784.

Would you please perform two simple tests to help me evaluate the electrical +condition of the counter? First, turn off the unit if it is powered on. Turn on +the unit and it should display a four (4) digit number. What is the four digit +number? ANSWER: It displays first number 1992. Then it displays two numbers 8572 and 04.04.

After the four digit number is displayed please press the "function" buttons up or down until the "check" lamp is lit. What, exactly, does the display indicate? ANSWER: it indicates 10.0000000 and then small 6.

I also verified that the rear 10MHZ OUTPUT works and produces output, with my oscilloscope.

It also has IEEE 488 output.
